Exposure to certain tastes can lengthen or shorten the life spans of fruit flies, leading researchers to wonder whether taste buds also affect human longevity. An inability to taste nutrients might lead to life-lengthening adaptations.

Scientists discovered the bones of seven huge dinosaurs that each weighed more than a dozen elephants and had femurs bigger than a human adult. Found in Argentina, the beasts may represent one of the biggest dinosaur species known to science.

Visitors to Jennette's Pier in Nags Head, North Carolina, were shocked last week when an evil-looking fanged fish washed up alive on the shore. The monstrous fish has been identified as a long-snouted lancetfish, a species rarely seen on coasts.

A newly reformed "tree of life" for anemones revealed an errant branch: It turns out that one of the creatures classified as an anemone is actually the first discovered in a new order of animals, the equivalent of the first member of primates.

The ongoing collapse of shark populations has already had far-reaching effects on marine ecosystems. To arrest this trend we need scientific data that effectively inform conservation management. But are we focusing our research effort in the right areas?

Octopuses are not in complete control of their arms, but evolution has devised a clever and simple way to prevent them from getting tied in knots: Something in their skin prevents their own suckers from grabbing on.

In a chance discovery, scientists found the first images of a dead whale shark and three dead rays on the bottom of the Atlantic Ocean. Though "fish falls" are common, it's very rare for scientists to find these sunken carcasses.

The amazing diversity of sea anemone, stationary animals that typically live on the seafloor or coral reefs and are related to corals and jellyfish, comes to light in stunning images.
